This bug makes using Adobe in an office a nightmare! Offices love forms with page long text boxes. Users are loosing hours of work and ripping their hair out and shouting obscenities at Adobe software in our office.. and I've done it too :( :(

This is VERY annoying as I must unlearn a habit I formed over many years with previous versions.

I have finally cracked up a solution. First of all uninstall Acrobat from Creative Cloud. Then head to this link from Adobe:

https://helpx.adobe.com/download-install/kb/acrobat-2020-downloads.html

and download the 2020 version. Install this one and sign in with your subscription credentials! Et voila! The old beloved ESC function and a speedy pdf editor is back in the game! I hope this helps everyone!

Adobe seems to go out of its way to break the long established methods of working. When I get out of bed in the morning, just once a day, I want the floor to be in the same place. I make comments while editing pdf scripts perhaps hundreds of times a day. I do not want Adobe to move the floor.
Give us back the simple, well established, use of ESC to accept and close a comment.

Please return to the old behavior. There is no utility to have a shortcut to discard her/his own comments. Discarding own comments is not an action occurring often, and requires no shortcut!!

On the other hand, I wrote a long thoughtful comment on how a paragraph should be rewritten, by all means I do not want it to be lost just because I pressed inadvertently the ESC button! When this happens, it is so annoying to retype the comment a second time.

I really depend on this functionality as well. And it's still documented in the old way on Adobe's own website. Workarounds are available, but they're only workarounds.

I'm just joining the group of "stupid users" who thought pressing ESC would just close the comment box instead of irreversibly discarding the comment without a single warning. Oh, my bad: the stupidity is actually on the developer who never took a single lecture on how to design UI -- in particular, the one that covers "destructive actions" (a tip: https://uxpsychology.substack.com/p/how-to-design-better-destructive)

This Bug is now here for more than a year and still the issue exists. I do not understand why this has not been fixed already! People using this software are really struggling with this and deleting comment after comment!
FIX THIS PLEASE!

really need this!

It makes PDF pretty much useless for critical tasks involved in editing and publishing. Reviewing academic papers, making a literature review, etc. one woluld think this is such a commonly employed feature and thus such a central service of the programme that they would be careful not to mess with it. Why, wouldn't you know it? It doesn't work. Thank God for PDF alternatives like Foxit. This nonsense is the creation of absolute idiocy.

It's not just comments, it also applies to forms with large text boxes for input!
You spend hours filling out a detailed response to a question, hit ESC, and its ALL GONE!
WTF!!

I just lost an hours worth of work simply because I hit ESC while writing!?
I now despise Adobe products even more because of idiotic bugs like this!
No other software behaves like this!
*FRUSTRATED*

Just returned to proofing after time away, this change is time-consuming over a day's work, even without the comments I keep losing. Please give us the Escape-to-commit back!

Why should the teenage geeks change a feature that has been useful and accepted for decades? Why even consider such absurdities?
What a crass decision! Change for change sake while disrupting the workflow of many/most users.
Put it back to the previous method.

This is a counterproductive and silly behavior.

This is the most counter-productive thing you have ever implemented for professional users of Acrobat. There should at least be the option in the preferences section.

This is a HUGE flaw in the latest update. I make a lot of comments/mark-ups quickly as a physician in charge of teaching medical students. To have to click "post" instead of simply hitting "escape" was probably the primary reason I chose an Adobe subscription instead of any other PDF reader/editor. But whereas I used to be able to open a PDF, open the comment sidebar, highlight text, automatically fill out the comment text, hit escape and have it save, now the entire comment is deleted. FIX THIS NOW.
